RULING: A pitching and base-running infraction have occurred at virtually the same time and both are penalized.
R1 is out for leaving the base before release of the pitch; an illegal pitch is called on F1 for failing to deliver the pitch, which results in a ball being awarded to B2. However, if in the umpire’s judgment, F1’s act was deliberate to bait and deceive R1 into leaving the base early, the umpire shall call “time” and “no pitch.” The umpire shall eject F1 and/or the head coach from the game. If the umpire believes the coach is directly responsible for the actions of F1, the umpire may eject only the coach. The defensive team is attempting to benefit by circumventing the rules. R1 is obliged to stay in contact with the base until the ball is released by the pitcher; however, the tactic being utilized by the defense is deceptive and not in accordance with the spirit of fair play. (3-6-13b, c; 6-2-1; 8-6-21)

So there is some intrep for intent to cause the offense to leave early where the umpire could not call the runner out based on F1's actions.

Not that anyone cares, but I'd still like to negate the out without having to eject the pitcher!
